Themes allow the user to change the look-and-feel while remaining within the same customization.

Within a customization, you can define one or more themes. Within a theme, you can define one or more theme parts. Together, the themes and theme parts determine how the application is displayed. For example, you can have one theme that displays items using a green color palette, and another that displays using a blue color palette. For more about the principles behind themes and theme parts, see Customization fundamentals.
